As you can see you are knitting to one stitch less than in the previous row every time. These 26 rows form one "wedge". Repeat 6 more times. (7 wedges in total).

Finishing: Fold cloth with right sides together, cast on edge held behind the needle. Knit 1 loop from needle, one from cast on dege to form one stitch. Cast off in the usual manner, knitting the cast on and cast off edges together as you do so. Sew in ends, and draw up center of cloth.

Checkerboard Washcloth

Rating: Easy

Materials: Use a sport to worsted weight cotton, (1 - 50gram ball or less) and #3or #4 US needles.

Instructions:

Cast on 46 stitches.

Row 1: Knit across to last 3 stitches and slip them one at a time, with yarn in front, to the right needle.

Row 2 - 4: Repeat Row 1.

You now have 2 ridges of garter stitch with the beginnings of an applied I-cord border.

Row 5: K3, *k4, P4, repeat from * to last 3 stitches and slip them, with yarn in front, one at a time to the right needle.

Row 6 - 10: Repeat Row 5.

Row 11: K3, *P4, K4, repeat from * to last 3 stitches and slip them one at a time to the right needle.

Row 12 - 16: Repeat Row 11.

Repeat Rows 5 - 10.

Repeat Rows 11 - 16.

Continue in checkerboard stitch, working applied I-cord at the edges, until piece is square.

Continuing to work I-cord edge, work 4 rows garter stitch (all knit).

Cast off. Done!

Run the tails of yarn down through the little I-cord tubes at the sides - they're very well hidden there.

I think the alternating knits and purls help keep this washcloth from stretching too far out of shape the way an all garter stitch cloth can. A very utilitarian pattern!
